Rainbow rings around lights, peripheral vision, macular are fine

I don't want to start conventional treatment.I have cataracts and diabetes and allergies.operations are not on my calender.I am scared.I am in really good health strangely enough.I am gluten free,lactose and sulphite free eater and organics and have managed my diabetes with supplements. I am for the first time feeling not in control.Books have been 60% of my life,to me not seeing is death.My hospital appointment is for towards the end of this month when I will have a field test. I would like to see someone whose approach to health is not rigidly conventional.
